AUDIORAMA - Testes sobre potência real dos receivers, Potência 100W x5

CATÁLOGO DE EQUIPAMENTOS DE AUDIO & VIDEO

MODELOS NOVOS, ANTIGOS & RAROS, FORA DE LINHA & DESCONTINUADOS

Potência Real: Será que "100Wx5" do seu Receiver são mesmo 100 Watts x5?

Fato: Praticamente todos os fabricantes de Receivers multicanal para Home Theater apresentam números de potência muito semelhantes, por exemplo, quase todos dizem ter "100W x5".

Dúvida: Será que esta potência declarada pelo fabricante é real? Será que é apenas um artifício de marketing, usado como "número mágico", para poder vender mais? Será que estes Receivers fornecem mesmo toda a potência que está descrita em seus manuais?

Veja abaixo os testes de alguns equipamentos de marcas renomadas.

Compare o que diz o fabricante e o que os testes em laboratório revelaram.

Testes de medição de potência feitos em laboratório, em condições normais de uso, isto é:

Modo Multicanal, com 5 canais funcionando simultaneamente.
Modo Multicanal, com 7 canais funcionando simultaneamente.
Modo Estéreo, com 2 canais funcionando simultaneamente.

COMENTÁRIOS:

Já imaginou um automóvel "Uno Mille" (original de fábrica) andando a 200Km/h?

"Pois é, eu garanto a você que já vi isso.

(Só não te conto que ele estava descendo uma enorme ladeira...)"

Nesta situação hipotética isso seria uma verdade e esta informação da

velocidade máxima poderia até constar no manual do veículo, não é mesmo?

E assim também são os números declarados pelos fabricantes de equipamentos de áudio.

É preciso seguir alguns PARÂMETROS nas medições, dizer COMO foi feito o teste, em que condições

se chegou àqueles números das especificações técnicas apresentadas no manual do equipamento.

Alguns parâmetros adotados pelos fabricantes que podem "mascarar" informações e induzir o consumidor a uma interpretação errada sobre potência:

Medir a potência com apenas 1 canal funcionando.

Medir a potência com impedâncias mais baixas que o padrão de 8 ohms (usar 6 ou 4 ohms).

Medir a potência com níveis de distorção elevados (acima de 1%, ou nem citar este dado).

Medir a potência somente em uma determinada freqüência, 1 kHz por exemplo.

Medir a potência em Watts "PMPO" ou Potência Dinâmica ou Potência Musical.

Omitir o consumo máximo de energia elétrica do equipamento funcionando a plena potência é outro hábito corriqueiro.

Não medir a potência e colocar qualquer valor ou aquilo que o departamento de marketing achar melhor para aquele aparelho... afinal quem vai desconfiar?

Parâmetros teoricamente corretos para medição de potência, adotados pelos fabricantes mais sérios:

Medir a potência de saída com todos os canais funcionando simultaneamente.

Medir a potência com impedância padrão de 8 Ohms.

Medir a potência com níveis de distorção baixos, até 0.07% ou menos.

Medir a potência em toda faixa de freqüência audível, de 20Hz a 20kHz.

Medir a potência contínua, expressa em Watts RMS

Medir a potência com alimentação constante da rede em 120V (ou 220V)

A indicação do consumo total de energia elétrica do equipamento funcionando a plena potência costuma dar credibilidade as informações sobre os watts reais de potência fornecidos pelo Receiver, assim como o peso do equipamento nos dá uma pista sobre o tipo de fonte de alimentação (transformador) e a sua capacidade de fornecer energia suficiente para a etapa de amplificação do Receiver.

*Falando a grosso modo: Um equipamento de som não "fabrica" energia, apenas transforma a energia elétrica em "som", e com algumas perdas neste processo. Logo, um equipamento deve ter um consumo de energia MAIOR que a potência total entregue em forma de som, nunca o inverso.

Exemplo: Receiver "A"

Potência de saída: 100W x5 = 500W de "som"

Consumo máximo = 850W de "energia elétrica"

CONCLUSÃO: Nem sempre o que se lê nas especificações é a pura verdade. Provavelmente, alguns fabricantes "se renderam ao departamento de marketing", mascarando alguns números nas especificações técnicas ou omitindo certas informações para poder concorrer de igual para igual na hora de anunciar seus produtos a venda.

Porém, quando se ouve dois equipamentos lado a lado, a verdade é uma só: Muitas vezes temos Receivers honestos com apenas 40 ou 50 Watts RMS por canal dando um verdadeiro "baile" de desempenho e qualidade em cima de outros Receivers de marcas famosas com supostos 100 ou 120 Watts por canal, mas que não tem qualidade alguma...

Alta potência nem sempre significa melhor qualidade de áudio.

Se você deseja montar um sistema de áudio de alta qualidade prefira os equipamentos (amplificadores e Receivers) com baixa taxa de distorção harmônica.

Por exemplo, um equipamento de som com até 1% de distorção harmônica (THD) soará melhor que outro equipamento com 10% de distorção, independente do nível de potência dos amplificadores.

O ouvido humano já consegue perceber a perda de qualidade do som com distorções harmônicas acima de 1%. Imagine com uma distorção de 10%! Você escutará apenas barulho, com esta alta distorção será um áudio de péssima qualidade.

Fique atento aos seus ouvidos, eles são o melhor parâmetro na hora da compra. Depois de escolher o seu Receiver, só para matar a curiosidade, leia também o que dizem as especificações do fabricante, afinal isto não importa muito depois de saber como estes números são mostrados ao consumidor, principalmente aqui no Brasil.
